摘    要:目的探讨"2×4"矫治技术在矫治替牙期前牙反中的矫治效果。方法上下两侧磨牙上制作带环,上下4颗切牙粘贴托槽,视前牙拥挤度选择0.014或0.016英吋的镍钛圆丝排齐前牙。用0.016英吋的澳丝上颌弓丝在颊面管近中端弯制停止曲,停上曲紧抵颊面管,弓丝前端离开前牙唇面2.0 mm入槽结扎。下颌弓丝双侧侧切牙远中端弯制牵引圈,配合Ⅲ类牵引以解除前牙反。结果 16例替牙期前牙反病例经"2×4"技术矫治后均获得满意效果。结论 "2×4"矫治技术配合Ⅲ类牵引,能有效地解除前牙反,改善面型,促进上颌骨的正常发育,抑制下颌前伸。是替牙期前牙反矫治中一种方便、有效的矫治技术。

Abstract:Objective To study the orthodontic treatment of "2×4" in anterior crossbite of mixed dentition.Methods Make bends in the molars on upper and lower sides,the four incisors were bonded with brackets,choose 0.014 or 0.016 inch of nickel-titanium round wire aligned on the anterior teeth based on the congestion degree of them.Use 0.016 inch of Australian wire of maxillary arch edgewise to bend stop flex on the buccal band of mesioend,put against the buccal band strictly with stop flex,the front end of arch edgewise leaves 2.0 mm from the contour of bitcrown and then ligates.The distalend of the bilateral lateral incisor of mandibular arch edgewise bends elastics,together with ClassⅢ traction to relieve anterior crossbite.Results Sixteen patients with anterior crossbite of mixed dentition got satisfactory results after the treatment of "2×4" orthodontic.Conclusion Combined with ClassⅢ of intermaxillary traction,"2×4" orthodontic could treat the anterior crossbite of mixed dentition well,improve the face,make maxillary develop normally and prevent the mandibular protrusion.It might be a convenient and effective orthodontic technique in the treatment of anterior crossbite of mixed dentition.
Keywords:"2×4"orthodontic Mixed dentition Anterior crossbite ClassⅢ of intermaxillary traction
